Oryza granulata is one of China's three wild rice germplasm resources. Compared with Oryza rufipogon and Oryza officinalis, it exhibits more distinct scarcity and endangerment status and utmost importance in protection.At present, the research on the theory of wild rice protection and the development of protection technology were relatively lagging behind, which results in insufficient support for both ex-situ protection and in-situ protection.Based on the results of many years of experiments，the standard technical regulation for ex-situ conservation of oryza granulata resources in Hainan Province was summarized and normalized.It mainly includes terminology and definitions,the save procedures, field management, monitor,harvest,upgrading and revitalizing and propagation and multiplication,distribution,, management of germplasm information, so as to provide technical reference for ex-situ conservation of oryza granulata resources.The technical regulations are applicable to ex-situ conservation of oryza granulata resources in Hainan Province.
